The Correct option is A

Explanation with High Yield Facts :

Agenesis of the Corpus Callosum (ACC) is a rare birth defect (congenital disorder) in which there is a complete or partial absence of the corpus callosum. Agenesis of the corpus callosum occurs when the corpus callosum, the band of tissue connecting the two hemispheres of the brain, does not develop typically in utero. In addition to agenesis of the corpus callosum, other callosal disorders include hypogenesis (partial formation), dysgenesis (malformation) of the corpus callosum, and hypoplasia (underdevelopment) of the corpus callosum.

Signs and symptoms:

• Signs and symptoms of Agenesis of the Corpus Callosum and other callosal disorders vary greatly among individuals.
• However, some characteristics common in individuals with callosal disorders include vision impairments, low muscle tone (hypotonia), poor motor coordination, delays in motor milestones such as sitting and walking, low perception of pain, delayed toilet training, chewing and swallowing difficulties, early speech and language delays, and social difficulties.
• Recent research suggests that specific social difficulties may be a result of impaired face processing.
• Unusual social behavior in childhood is often mistaken for or misdiagnosed as Asperger's syndrome or other autism spectrum disorders.
• Other characteristics sometimes associated with callosal disorders include seizures, spasticity, early feeding difficulties and/or gastric reflux, hearing impairments, abnormal head and facial features, and mental retardation.
